Methylphenidate is the drug most frequently used in the treatment of attention deficit hyperactivity disorder. However, due to its psychostimulant properties, this substance has been used to stimulate productivity and increase intellectual capacity in several areas of study. In this work, the characteristics of the use of methylphenidate among pharmacy, nursing, and medical students of a university in the capital of Bahia were analyzed. In this cross-sectional study, 338 students from different semesters of the aforementioned courses were interviewed. The instrument used for data collection was a standardized self-completed questionnaire applied by the researchers. Altogether, 76% of respondents were female and the average age was 22 years old. The frequency of students who used or who had already used methylphenidate at some point in their academic life was higher among medical students (12%). The main justification for the use of this substance was the higher concentration to study (59%). Also, 92% of respondents claimed to use Methylphenidate without medical supervision and 80% indicated the time of the tests as the time of greatest use of this drug. These results show high non-prescribed use of methylphenidate among health care students.
Trauma is a public health problem, with a high morbidity and mortality profile that generates high costs for health systems all over the world. Several factors can trigger the different types of trauma, which may require specific treatments, often even surgical procedures, and may also cause incapacity for work. In light of this, this research was intended to evaluate the epidemiological profile of patients with traumas in different regions of the world. To this end, a systematic literature review was performed by searching the Scielo database, using the descriptors “trauma” and “epidemiology”, finding a total of 270 articles. Subsequently, filters were applied, which allowed 92 scientific articles to be obtained. The titles and abstracts of these articles were analyzed; and, from that, 15 articles were selected, which were read in full and then discussed. The literature analysis allowed us to characterize the epidemiological profile of traumas in Brazil and in other countries around the world, detecting that most trauma affects men at a young age, which can affect the labor system; that the low level of education can influence the trauma profile; and that factors such as car and motorcycle accidents, falls and physical aggressions are the main etiological factors of cranioencephalic, maxillofacial, thoracic, upper limbs and lower limbs traumas, among others. Thus, there is a need to formulate better preventive measures and pre- and in-hospital treatments, aiming at reducing the impact on trauma morbidity and mortality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
